Based upon the poll results I have to say that I'm amazed that so many believe that certain races are inferior to others.
However, IQ has been demonstrated to flow as well from environmental factors - and certainly none of us would argue that ones ability to apply ones' intelligence to the world around them is heightened or lowered by environment - the mind can be exercised and strengthened like a muscle.
To define it within "races", however, is overly simplistic. Even if one was arguing for a straight nature response, the genetic variation within the races is too wide.

And what are these studies? Link please.And IQ difference of a Statistically Significant nature; 1 Standard deviation or More (3) in some cases/between some races.
That's the 1 std deviation difference the other posters dispute. And this gap is decreasing.
1. The Worldwide Pattern of IQ Scores. East Asians average higher on IQ tests than Whites, Both in the U. S. and in Asia, even though IQ tests were developed for use in the Euro-American culture. Around the world, the average IQ for East Asians centers around 106; for Whites, about 100; and for Blacks about 85 in the U.S. and 70 in sub-Saharan Africa.
There are questions about the validity of the studies that claim the 50% heritability of IQ as well: The heritability of IQ. [Nature. 1997] - PubMed - NCBI3. The Gene-Environment Architecture of IQ is the Same in all Races, and Race Differences are Most Pronounced on More Heritable Abilities. Studies of Black, White, and East Asian twins, for example, show the heritability of IQ is 50% or higher in all races.
A lot of studies in the past don't properly account for the womb environment and the mother's physical condition during pregnancy. Studies that measure IQ after birth will tend to have this problem since it's very hard to isolate these factors and genes without actually looking at the genes itself.
This is a common heuristic problem. It's like saying: P(A/B) > P(A/B') and P(B/C) > P(B>C') and therefore P(A/C)>P(A/C'), P(A/C) might be bigger than P(A/C') but you have to measure that to know for sure, inferring from the probability of the first two is not always correct.4. Brain Size Differences. Studies using magnetic resonance imaging (MRI) find a correlation of brain size with IQ of about 0.40. Larger brains contain more neurons and synapses and process information faster. Race differences in brain size are present at birth. By adulthood, East Asians average 1 cubic inch more cranial capacity than Whites who average 5 cubic inches more than Blacks.
If I gave you these statements:
Probability of getting false positive is higher with ovary cancer than non-ovary cancer
Probability of getting ovary cancer is higher in older women than in younger women
It doesn't follow that the Probability of getting a false positive is higher in older women.
Here it's easy see that one of the factors that confound the third probability is the background probability of getting ovary and non-ovary cancer among the two groups of women. If older women are also more likely to get non-ovary cancer, and the probability of false positive is low enough in non-ovary cancer, then it's not true that older women are more likely to get a false positive. Likewise in reading the probability of intelligence. How much does brain size explains intelligence? If it's small enough, it doesn't follow that having a smaller head size will result in less intelligence if it's overtaken by other factors that affect intelligence. If brain size explains most of our intelligence, then we should expect to find men are much more intelligent than women since their brain is much bigger - but they are not.
This is the same roughly 1 std deviation difference and still doesn't account for what happens in the womb and before adoption, or the effect of racial identity. The author themselves wouldn't say that it's due to genetic differences.5. Trans-Racial Adoption Studies. Race differences in IQ Remain following adoption by White middle class parents. East Asians grow to average higher IQs than Whites while Blacks score lower. The Minnesota Trans-Racial Adoption Study followed children to age 17 and found race differences were even greater than at age 7: White children, 106; Mixed-Race children, 99; and Black children, 89.
The fact of the matter is that these studies all have differences that are not statistically significant and do not properly control for other environmental factors. To use them as if they proof anything conclusively is unscientific.
People are equal in absolute terms and not equal in nominal terms.
Don't dodge this question. You're making a serious claim here, at least to me, that I don't understand what I'm writing about. You would be doing a great service to your fellow liberal creationists on this board to show me up as the fool that you think me to be. Your mouth has led you to make this challenge so demonstrate for us that you understand the process of how population level genetic variance is induced and what processes outside of evolution you have in mind when you made your charge.
There is only one process that could plausibly be considered "outside" of the processes which comprise the driving factors of evolution which is powerful enough to induce some population level genetic variance and even this process is rightly a subset of one of the principal drivers of evolution.
